This is about a case that was solved 2 months ago WD20NMVW-11EDZS78 heads and one of the head was totally AMNF

Process used to recover data without a transplant1)USB board changed to SATA2)Backed Up ROM3)Bypass SA4)Relo was full, cleared it, unlocked SA in 02 permanently and did a slow read fix(can omit this at this step too ie the slow read fix)5)Reflashed original ROM6)Connect to DDI, Did a head map7)Media test showed one head goneDisabled that head in the DDI config.9)Connected Drive to DFL, repatched 02 so now the SA is locked again, did Slow read fix.10)NOW drive is again sa locked but DDI can work with the head map and disengage the faulty head while recovering the data from others at full speed.

Is there any way I can fix the AMNF error logically.. Have not tried to run the translator...Data is dispatched, can afford to experiment.

Hi, No DFL SRP that I have is just for FW.May be the person who has the Imager by DFL can comment more whether decrypt on the fly is available.....THIS DRIVE IS SA Lock + SED...the drive is giving data with original unlocked 02 where only slow read fix is done by executing slow read fix command...the moment one unlocks the SA, data is encrypted... It gives decrypted data over the SATA board with the SA locked....So the MCU is in charge of decryption and encryption process....Any way i can do a slow read fix + SA unlock without tampering with the bits/flags that take charge of MCU based encryption?.... DDI works good with such cases.....I am looking for some class 100 or class 10 FFUs....lets see how far I go with the build. I have a deep background of CAD work and have made a DIY CNC of C3 grade in past.So i believe I can surely do a DIY laminar flow.

Pray for me

To add, I wrote this case study after solving one more case today where only 200Gigs of data is required by a photographer client. Job finalized in 111.111USD (what a figure)This client of mine is 21 year old photographer who did some corporate shoot of a rest-0-bar/grill and now his name and repute is in jeopardy.
